I hope my question is within the topic of this group.

Could anyone tell me if glass tubing can be fused to stainless steel
tubing with a hermetic seal?

If so, are there special techniques/methods that need to be followed?

Would a scientific glass blower be able to do this.

Any advise appreciated.

You might want to enquire with http://www.indium.com/ . Indium is used
in solders which can be used to solder glass and to form glass to metal
seals. It's not cheap though at least in small quantities last time I asked.
